Benefits of technology

The present invention provides an LED light bulb that is simple and low-cost to manufacture. This is achieved through a transparent stem and seat that are connectable through rigid conductive wires, which eliminates the need for prior embedding and reduces manufacturing costs. The transparent lampshade and stem are made of plastic, which is not vulnerable to open flames and improves production safety. The sealant used in the light bulb effectively improves waterproof performance. The external threaded segment on the assembly portion improves connection stability between the lampshade and base.

Problems solved by technology

Conventional light bulbs are usually tungsten light bulbs using tungsten wires as light-emitting components; they are relatively high in power consumption, relatively low in brightness and high in heat emission.
However, the majority of LED light bulbs usually use a translucent but not transparent lampshade, which is quite different from conventional light bulbs in terms of outer appearance.
Although some LED light bulbs use transparent lampshades, their LED filaments are usually mounted directly on the stems and it is necessary to embed rigid conductive wires on the stem beforehand (e.g. embed during sintering, thereby resulting in complicated manufacture and relatively high costs.
Besides, lampshades and stems of existing light bulbs are usually made of glass which is vulnerable.
This induces certain safety risks.

Abstract

The present invention provides an LED light bulb comprising a transparent lampshade, a base, a transparent stem, a transparent seat, a power supply board fixedly mounted on the transparent seat, a first rigid conductive wire passing through the transparent stem, second rigid conductive wires passing through the transparent stem and connecting to the power supply board, and LED filaments fixedly connected to the first rigid conductive wire and the second rigid conductive wires. The second rigid conductive wires are two in number. The LED filaments are two or more in number. Each of the LED filaments are evenly distributed around the transparent stem, and each of the second rigid conductive wires is connected to at least one of the LED filaments.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a light bulb and more particularly pertains to an LED light bulb.[0002]Conventional light bulbs are usually tungsten light bulbs using tungsten wires as light-emitting components; they are relatively high in power consumption, relatively low in brightness and high in heat emission. Therefore, tungsten light bulbs are gradually replaced by LED light bulbs. However, the majority of LED light bulbs usually use a translucent but not transparent lampshade, which is quite different from conventional light bulbs in terms of outer appearance. Although some LED light bulbs use transparent lampshades, their LED filaments are usually mounted directly on the stems and it is necessary to embed rigid conductive wires on the stem beforehand (e.g. embed during sintering, thereby resulting in complicated manufacture and relatively high costs.[0003]Besides, lampshades and stems of existing light bulbs are usually made of glass which is...
